In the current context of rapid development of the new energy market, coupled with the rapid development of intelligence, a large number of domestic and foreign brands have joined the wave of car manufacturing, making the new energy vehicle market a hot topic. Related news is coming one after another, making us wonder about the current situation of automotive manufacturing quality?

For car users, facing road traffic directly, the safety factor of the car must be foolproof. As for the small fasteners and bolts of cars, insufficient or excessive tightening torque can cause certain damage to the car components, and in mild cases, it can lead to car breakdowns and customer dissatisfaction; In severe cases, road accidents may occur, posing a threat to personal safety. The tightening torque of fastener bolts is very important.

In physics, the magnitude of torque is equal to the product of force and arm of force, and the international unit is N * m (Newton meters). The torque required to tighten a screw is determined by the screw (or nut) itself, the tightening target, and the working condition. Therefore, in order to accurately grasp the torque required by electric screwdrivers for fasteners, it is necessary to pay attention to the early tightening work. During the testing stage, a torque tester can be used to read the values and determine whether it is compliant and safe.

As a national high-tech enterprise, SUDONG, a fast acting intelligent tightening technology, has taken the lead in mastering the core algorithm of digital tightening and has constructively proposed the concepts of "intelligent tightening" and "digital tightening" in the industry. With advanced research and development capabilities, SUDONG creates leading digital tightening technology, one-stop solution services, and intelligent tightening tools, focusing on industries such as automotive tightening shafts, hoping to make customers more efficient, precise, and safe Complete product production more intelligently.

Brushless intelligent electric screwdriver

The quick acting SUDONG brushless intelligent electric screwdriver is based on servo control and torque sensor technology, and its torque accuracy for millions of tightening assemblies is accurately controlled within a standard deviation of ≤ 3%. It can achieve free programming during the tightening assembly process, and within the performance parameter range, it can freely set and adjust torque, speed, waiting time, and rotation direction according to different tightening process requirements, achieving precise tightening. The internal use of a fast acting SUDONG brushless servo motor significantly reduces operating costs, has a longer lifespan, and ensures robust power performance and torque peak output, making it an ideal digital tightening assembly process choice.

Torsion tester

The torque tester is mainly used to test the tightness of the sample and the torsional performance of certain components of the sample, in order to determine whether the sample meets the torque requirements.

The Quick Action Intelligent Tightening Torque Tester is the industry's first comprehensive tester that integrates torque, speed, and angle. Patent number: ZL201620691658.6, model SD-TST-10 has a torque range of 1.5-10 (N * m), and model SD-TST-1 has a torque range of 0.15-1 (N * m). With a new design concept, it integrates industrialization and humanization, making operation and use more efficient while bringing more convenience.

The tester adopts a 2.5-inch LCD display, with multiple data displayed on the same interface. Reading torque values is more intuitive, eliminating the need to switch interfaces when filtering data. At the same time, without the need for user calculation, the maximum, minimum, and average values of torque can be automatically confirmed, and the accuracy of torque testing reaches 0.5%, striving for accurate data. By connecting to a computer through a USB port, torque output curves and speed curves can be drawn. The computer can store unlimited sets of test data, providing users with more convenience.

Adhering to the service philosophy of pursuing innovation, QuickAction Intelligence will continue to innovate and research and develop tightening tools, providing advanced tightening tools for our customers, helping to rapidly leap forward in the Industry 4.0 era, and promoting social security, stability, and harmonious development.
